If you ever wrote a book... did it end being published? How many of them were printed?

Can you partake how it happened in you to write a book? Did you take a course or did you train with some expert on how to do it in a near-professional way? What gives to a person to decide to write? Only explore one's ability to structure an imaginary life, an event or several into structured and interesting narration? Are book writers out of the ordinary IQ gifted or average smart people? What do their brain carry different from the other normal brains?
